Laparoscopic-guided biopsy of pancreatic transplant allograft.
Percutaneous and transcystoscopic transplanted pancreatic graft biopsy have now become the best methods in diagnosing graft rejection and dysfunction. We report our technique of laparoscopic pancreatic graft biopsy in a case not amenable to standard trancystoscopic or percutaneous biopsy.


METHODS
A 44-year-old man underwent enteric conversion of a previous combined bladder-drained kidney-pancreas transplantation for repeated episodes of dehydration. Complaints of polyuria and polydipsia necessitated biopsies of the grafts to rule out graft rejection. The ultrasound of the pancreas, however, showed multiple bowel loops overlying the graft preventing percutaneous biopsy. The patient was taken for laparoscopic-guided pancreatic graft biopsy.


CONCLUSIONS
Enteric-converted pancreatic grafts are not amenable to transcystoscopic biopsy. These grafts are often covered with loops of small bowel preventing ultrasound-guided percutaneous biopsy. Until recently, open laparotomy was performed to biopsy these grafts. We present our method of laparoscopic-guided pancreatic graft biopsy as an alternative to open laparotomy.


CONCLUSIONS
Laparoscopic guided biopsy for pancreatic allograft transplantation is a safe and effective alternative to open laparotomy and should be considered when percutaneous biopsy is hazardous or not possible.
